Solid glass beads for use in isolating cell membranes were coated with a stable, covalently attached layer of polylysine. The optimal conditions for coating the bead surface were established and the beads were tested by measuring the attachment of human erythrocyte plasma membranes. When compared to other beads, such as those with absorbed polylysine or protamine, none retained red-cell membranes as well as glass beads with covalently linked polylysine.
用于分离细胞膜的实心玻璃珠涂有一层稳定的、共价连接的聚赖氨酸。确定了包被珠表面的最佳条件，并通过测量人红细胞质膜的附着情况对珠子进行了测试。与其他珠子（如吸附有聚赖氨酸或鱼精蛋白的珠子）相比，没有一种珠子能像带有共价连接聚赖氨酸的玻璃珠那样保留红细胞膜。
